## Discrepancy

PILOT WAS GOING INTO A HOVER DETECTED SOMETHING BURNING, AT THE SAME TIME LOST ALL RADIO AND ICS COMMUNICATIONS.  PILOT PUT THE ACFT BACK DOWN AND NOTICED HIS PILOT ICS CIRCUIT BREAKER POPPED. AFTER EXTENSIVE TROUBLESHOOTING, MX AOG ORDERED A 2 AMP CIRCUIT BREAKER (SOURCE OF BURNING SMELL) AND REPLACEMENT AUDIO PANEL (CAUSE OF CIRCUIT BREAKER FAILURE). PARTS WERE INSTALLED AND ACFT WAS RETURNED TO SERVICE AFTER A SUCCESSFUL OPS CHECK.
